Cyproheptadine is a sedating (first generation) antihistamine that can relieve allergic symptoms from hay fever (rhinitis), allergic conjunctivitis due to inhaled allergens and foods and mild allergic skin conditions such as hives. Because it is sedating, it can also help with sleep disturbances caused by itchiness.
Cyproheptadine can be taken by mouth as syrup or tablets. Adults usually take 4-20 mg 3 times a day (every 8 hours). The maximum daily dose is 32 mg.
Common dosing schedule:
You can take Cyproheptadine with or without food.
Take Cyproheptadine at night if you become drowsy after taking the medication. (Daytime sedation can be relieved by taking non-drowsy antihistamines as alternatives.)
This schedule is for reference only, adjustments may be made according to individual needs.
